141 string "Default kernel command string"
144 On some platforms, there is currently no way for the boot loader
145 to pass arguments to the kernel. For these, you should supply some
146 command-line options at build time by entering them here. At a
147 minimum, you should specify the memory size and the root device
148 (e.g., mem=64M root=/dev/nfs).
150 config HEXAGON_ANGEL_TRAPS
151 bool "Use Angel Traps"
154 Enable angel debug traps (for printk's).
157 bool "Multi-Processing support"
159 Enables SMP support in the kernel. If unsure, say "Y"
162 int "Maximum number of CPUs" if SMP
167 This allows you to specify the maximum number of CPUs which this
168 kernel will support. The maximum supported value is 6 and the
169 minimum value which makes sense is 2.
171 This is purely to save memory - each supported CPU adds
172 approximately eight kilobytes to the kernel image.
175 prompt "Kernel page size"
176 default PAGE_SIZE_4KB
178 Changes the default page size; use with caution.
